192 in2
The formula for surface area is 2(lw + wh + hl) = 2(2*8 + 12*8 + 12*2) = 2(16+56+24) = 2(96) = 192
Answer:
2500 pence (C = 2500)
Step-by-step explanation:
![C = 10t + 20m](https://tex.z-dn.net/?f=C%20%3D%2010t%20%2B%2020m)
From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.
![C = 10(150) + 20m](https://tex.z-dn.net/?f=C%20%3D%2010%28150%29%20%2B%2020m)
Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.
![C = 10(150) + 20(50)](https://tex.z-dn.net/?f=C%20%3D%2010%28150%29%20%2B%2020%2850%29)
Now multiply the substitutes with the co-efficient.
(10*150=1500 & 20*50=1000)
Add the addends
C = 2500
Answer:you
Step-by-step explanation:
Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles. For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.
x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg. Thus, x/2 = 22.5 deg, and so x = 45 deg. (answer)
